No-spend challenge rules
Essentials stay: rent, groceries, bills, transport, medication. Everything discretionary freezes: takeout, impulse orders, subscriptions you would not re-buy today, "treat" purchases. A no-spend day means zero discretionary dollars left your account.
Handle slip days honestly
A slip day does not end the challenge — it just is not marked. The grid shows the truth either way, and an 11-of-14 challenge still saved you real money and showed you exactly where the leaks are.
Spending is a discipline problem
Most impulse spending is the same loop as scrolling or snacking: trigger, urge, tap. Treat it like any other discipline rep — make the urge visible, delay it a day, and let the saved total argue for you.
